/**
 * Class representing a data series in gnuplot. 
 * If a list <code>directives</code> of Strings is given, each of them
 * is interpreted in the following way: if it starts with either "title " or "t ",
 * it is considered a 'title' directive for the series;
 * if it starts with either "with " or "w ", it is considered a 'with' directive for the series
 * (consult the gnuplot documentation for further details).
 * Their order does not matter; they are correctly placed in the gnuplot command.
